S32750 Stainless Steel Tubing

Kufotokozera Kwachidule:

Aloyi 2507, yokhala ndi nambala ya UNS S32750, ndi aloyi yamitundu iwiri yotengera chitsulo-chromium-nickel system yokhala ndi mawonekedwe osakanikirana a pafupifupi ofanana ofanana austenite ndi ferrite. Chifukwa cha kuchuluka kwa magawo awiri, Aloyi 2507 imawonetsa kukana kwa dzimbiri ngati zitsulo zosapanga dzimbiri za austenitic zokhala ndi ma alloying ofanana. Kupatula apo, ili ndi mphamvu zolimbikira komanso zokolola zambiri komanso kukana kwa chloride SCC kuposa ma austenitic ake pomwe imakhala yolimba kwambiri kuposa ma ferritic.

Chiyambi cha Zamalonda

Super Duplex yosapanga dzimbiri ngati S32750, ndi mawonekedwe osakanikirana a austenite ndi ferrite (50/50) omwe apititsa patsogolo mphamvu kuposa magiredi achitsulo ndi austenitic. Kusiyana kwakukulu ndikuti Super Duplex ili ndi molybdenum ndi chromium yapamwamba kwambiri yomwe imapangitsa kuti zinthuzo zikhale zazikulu Kwambiri chromium imalimbikitsanso kupanga magawo owononga a intermetallic, omwe amakhudzidwa ndi 475 ° C chifukwa cha mvula ya gawo la α' lolemera chromium, ndi kulowetsedwa ndi sigma, chi ndi magawo ena pa kutentha kwakukulu.

Aloyi 2507 (S32750) imakhalanso ndi nayitrogeni wapamwamba kwambiri, zomwe sizimangolimbikitsa mapangidwe a austenite ndikuwonjezera mphamvu, komanso kuchedwetsa mapangidwe a intermetallic magawo okwanira kulola kukonza ndi kupanga kalasi ya duplex.

Kalasiyi imadziwika ndi kukana kwa dzimbiri kwa chloride, kuphatikiza ndi mphamvu zamakina apamwamba kwambiri. Ndiwoyenera kugwiritsidwa ntchito m'malo ankhanza monga madzi a m'nyanja ofunda a chlorine ndi media okhala ndi acidic chloride.

Makhalidwe a Aloyi 2507 (S32750) ndi awa:

● Kukaniza kwambiri kupsinjika kwa corrosion cracking (SCC) m'malo okhala ndi chloride
● Kutha kupirira potchinga ndi dzimbiri
● High kukana dzimbiri wamba
● Mphamvu zamakina kwambiri
● Maonekedwe akuthupi omwe amapereka ubwino wa mapangidwe
● Kulimbana kwakukulu ndi kukokoloka kwa dzimbiri ndi kutopa kwa dzimbiri
● Kuwotcherera bwino

S32750 idapangidwa kuti igwiritse ntchito zovuta zomwe zimafuna mphamvu zapadera komanso kukana dzimbiri, zomwe zimapezeka mumankhwala ndondomeko, zida za petrochemical, ndi madzi am'nyanja. Amagwiritsidwa ntchito kwambiri pofufuza mafuta akunyanja ndi gasi / kupanga komanso posinthanitsa ndi kutentha kwa petrochemical/chemical processing. Gululi ndiloyeneranso kugwiritsa ntchito ma hydraulic ndi zida zogwiritsira ntchito m'malo otentha am'madzi.
